Twist–torsion coupling in beating axonemes
Motile cilia and flagella produce regular bending waves that enable single-cell navigation due to non-planar waveforms with characteristic torsion.…

Topological interactions drive the first fate decision in the Drosophila embryo
During embryogenesis, the first cell fate decision—whether the cell participates in development of the embryo or not—is often linked to the pos…
Mechanochemical bistability of intestinal organoids enables robust morphogenesis
Reproducible pattern and form generation during embryogenesis is poorly understood. Intestinal organoid morphogenesis involves a number of mechanoc…
Marangoni-like tissue flows enhance symmetry breaking of embryonic organoids
During the early development of multi-cellular animals, cells self-organize to set up the body axes such as the primary head-to-tail axis. Several …
Measuring age-dependent viscoelasticity of organelles, cells and organisms with time-shared optical tweezer microrheology
Quantifying the mechanical response of the biological milieu (such as the cell’s interior) and complex fluids (such as biomolecular condensates) …
Controlling noise with self-organized resetting
Biological systems often consist of a small number of constituents and are therefore inherently noisy. To function effectively, these systems must …
